You would think it would be a dream location, living next door to a best-selling singer whose harmonic voice catapulted her to stardom on the U.K. reality competition "Britain's Got Talent."

Not so say the neighbors of Susan Boyle, who have filed a noise complaint against the singer for singing at all hours of the night, a situation they describe as "unbearable," according to the UK's The Sun.

The neighbors - Teresa Miller, 39, and her fiancé, Paul Keaveney, 44, say that Boyle, who has sold more than 14 million albums, spends hours belting out covers of 'Wild Horses,' 'Unchained Melody' and 'I Dreamed a Dream' while playing excessively loud music repeatedly.

"It is so loud you can't hear the telly," Miller told the Sun. "It'll be on first thing in the morning or late at night and it's absolutely blaring."

Proving themselves even tougher than the judges Boyle, 51, faced on "Britain's Got Talent," Simon Cowell included, Miller and Keaveney filed a complaint with the West Lothian Council this week.

West Lothian Council officials have declined to comment on the allegations against Boyle, who reportedly lives alone in the home with her cat.

A rep for Boyle confirmed to ABC News that both parties have been engaged in a long running feud for over a decade, classifying Millers' allegations as "old news."

Boyle, according to British media reports, lived in the Blackburn, West Lothian, home before she tried out for "Britain's Got Talent." She purchased a nearly $500,000 villa across town after her second-place finish on the reality TV talent show in 2009 but then returned to her original home six months later.

That, says Miller, is when things began to change.

"She was alright for a month or two but then she went to America and totally changed," she said. "I don't hate her. I feel sorry for her."

Boyle's friends say the couple's actions are nothing but retaliation for calls Boyle allegedly placed to police complaining about noise from Miller and Keaveney's home.

"These neighbors have been having almighty rows," an unnamed Boyle ally told the Sun. "Susan has been forced to call the police several times as she has been concerned that they might hurt each other. She was scared."

"It is nonsense," another friend told the Daily Mail. "Susan doesn't even do her practice in that house. She has her piano in what she calls her 'posh house' on the other side of town and does all her practice there. So it is very unlikely she would disturb these neighbors with her singing."
